Sarita, TX Coastal Erosion Rate
Shoreline change 25.2 miles east of Sarita, TX
25.2 miles east of Sarita, TX, the coast is advancing, not retreating, at a measured 0.88 feet a year, sediment accumulating faster than any erosion USGS recorded here. At that rate, the shoreline has gained roughly 8.8 feet over the last decade.
What "Sarita" means on this page
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Sarita, TX. Centered near 27.20°N, 97.39°W. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
25 years at this rate
Holding the 0.88 ft/yr accretion rate 25.2 miles east of Sarita, TX for 25 years would add roughly 22 feet of shoreline, again assuming nothing about the local sediment supply changes.
How solid is this number
This reading comes from 109 individual transects averaged together, 0% of which measured erosion rather than growth. Uncertainty on this specific number: 0.25 ft/yr either side. Among the 1211 US coastal segments with a measurable trend, this one ranks 1087 for erosion, 1 being the fastest-retreating coast in the dataset. Source: USGS Open-File Report 2004-1089. Pensacola Station, FL sits at national rank 1062 for growth (0.7 ft/yr), one reference point among the 1211 scored segments, 636 miles from here. Sarita, TX, 2.8 miles off, is the adjacent measured stretch, reading slight accretion (beach growing) at 0.58 ft/yr.
Not this whole stretch, just Sarita itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
